To all whom t may concern: f e

Be it known that ll, EDWARD A. KLIEWER, a citizen of the United States, residing at Fairview, in the county of Major and State of Oklahoma, have invented certain new and useful `llmprovements 'in WellCasing and rliool Fishing Devices; and l do declare the following to be va full, clear, .and exact description of the invention, such as will enable others skilled in the lart to which it appertains to make and use the same.

My invention has for its object to provide an extremely simple and inexpensive, yet a highly efiicient device for fishing tools and casings from wells, it being my intention to provide-means for connecting two i parted sectionsof thecasing, so that raising of the upper section will carry with it the lower section. I

With they foregoing general object 1n view,'the invention resides in the novel features of construction/and unique combina-- tions of parts to be hereinafter fully described and claimed, the descriptive matter fisc ma .being supplemented bythe accompanying .drawings which form a part of this speciication and 'in which:

Figure 1 is a side elevation of the tool partly broken away andin section showing it in use;

. Fig. 2 is an enlarged vertical section on the plane of the line 2-2 of Fig. l;

Fig. 3 is a perspective view of the form of the invention shown in Figs. 1 and 2;

Figs. 4 and 5 are horizontal sectional views on the planes of the lines 4-4 and 5`-5 of Fig..2;and j Fig. 6 isa perspective view showing a slightly di'er'ent form of 'thervinvention ln the drawings above briefly described, the numerals' 1 designate the individual "toothed yjaws of an outer series, said jaws bein adapted to'eXpand and grip the'cas-l ing as shown in Figs. 1 and l2. l Surrounded by the outer series of jaws, is an inner series of contracting jaws 2 having teeth for gripping the usual jar J when the latter carries on'its lower end a spear S fdt the proper time.

,.jttAr'ms 4 rise from the jaws l and `at 5 are pivoted in notches in the edge of a horizon- The from the jaws 2 and are suitably joined to specincaam of Leaersratent. P@mmfd Mmy gj,l jm, application mear'bruary'ai, 191e. smainouaiaiee.- j

Atubular cable guide 7 'is suitably secured to the center ofl the head 6 and depends therefrom, said y j guide bein received slidably in a 'central opening 8 ormed in the head 6'.. A- preferably arched suspending rod lorother device 9 is secured at 1 0 to the head 6 and rises slida'bly through-openingsll in the head 6,

the upper end of said suspendin device being .0H-set laterally fromthe aims of the tool in order that it may interfere in no manner-.with the usual cable 4G? which passes through the guide 7 and is vconnected to the jar J by the usual socket. 'l

in Figs. -1 to 5, or as seen 'in Fig. 6, the heads 6- and- 6 and the guide 7 may be Vforged in two parts to permit the tool .to be niore easily applied to the cable C2. In'either case,the

operation and advantages are similar.

In use, after the spear S 4has been lowered by the jar J and the cable -Cand properly 'llhe device may beconstructed as featured I engaged with the lower casing section C', the

connected by a vcord or other easily breakable connection CS. By means of the cable guide', the tool follows the cable C2 until the lower end of said guide strikes the upper endof the jar J located in the lower end of the upper casing section C. When this takes place, downward movement l of the upper head 6 of the jaws 1 is prevented, but head. 6 and its jaws 2 continue to .descend to such an extent as to` cause the wedge faces 3 to I contract said inner jaw 2 around the jar J and to simultaneously expand `the jaws 1 against the casing section C. 4 By now connecting the usual hoisting means tothe upper end o f said casing section C, this section may be raisedand through the instrumentality of the jaws 1 andQ, thejar J 1s forced to move bodily upward, with theresult that the spear S similarly moves the lower casing section C. At a suitable time,

the sand line lL is pulled suiiiciently hard.

to break the connection C? and it is then re-.

moved from the casing. This having beenA done, an ordinaryv cable cutting tool is lowered intothecasing. and the cable C2 1s severed -near its lower end. rFhese operations having been performed, the withdrawal of the casing is continued.
